Viscosity of saturated mixtures of 1-hexyl-3-methyl-imidazolium bis(trifluoromethylsulfonyl)amide with R600a and R152a

The mixtures of refrigerant/ionic liquids have been considered as a very promising working pairs in the absorption refrigeration system. In this work, the liquid viscosities of saturated mixtures of 1-hexyl-3-methyl-imidazolium bis(trifluoromethylsulfonyl)amide ([Hmim][Tf2N]) with isobutane (R600a) and 1,1-difluoroethane (R152a) were measured based on the viscosity experimental system developed by our laboratory. The system includes the modified...
